Question

Done. I researched it and rebuilt this as v1163, without undoing the v1158 P3 correction.

The important finding was that v1158’s problem was not that its P3 lift needed replacing. The missing piece was on the recent conditional evidence side. v1158 estimates qA from A’s losses and qB from B’s losses only. But once Match Winner is fixed, there is another independent-looking sample of the same conditional exact-score event that does not require changing Match Winner. The original v1158 structure already makes those q values the straight-set-vs-three-set split inside each fixed winner row. (TennisLocks_FINAL_v1158_BO3_CROSS_SET_RESPONSE_FIX_20260915.txt)

So v1163 now works like this:

qA = P(A steals a set | B wins) uses A's losses (1-2 vs 0-2) + B's wins (2-1 vs 2-0).
qB = P(B steals a set | A wins) uses B's losses + A's wins.
Sweep-heavy evidence therefore pushes P2 upward: favorite often wins 2-0 + underdog often loses 0-2.
Competitive evidence pushes P3 upward: winner often needs 2-1 + loser often loses 1-2.
The v1158 structural response, structural weighting, Match Winner anchor, Fréchet geometry, and exact-score reconstruction are unchanged.
If both Match Inputs contain the same recent H2H, v1163 de-duplicates it when the row fingerprints are available.
No population P3 target, fixed P3 cap/floor, corpus anchor, fixed pseudo-count, or raw win-rate blend was added.

This is much closer to what the research supports. A 66,262-match BO3 study finds both strategic and psychological set-level effects, so the evidence does not justify forcing every match toward either comebacks or sweeps. (Sage Journals) Ingram's point-based work models player strength as changing over time, supporting your matchup-specific point root remaining the structural authority rather than replacing it with historical set frequencies. (IDEAS/RePEc)

I also rejected two ideas from the experimental v1162 work instead of blindly promoting them. I did not replace your existing structural weight with a beta “pseudo-sample size,” and I did not let official opponent rank directionally mutate q. Gollub's tennis work supports opponent adjustment using serve/return ability, while research comparing rating systems finds official rankings relatively poor compared with Elo-based measures. Your point model already has opponent-specific serve/return information, so adding a rank-driven direction on top risked double-counting opponent strength. (Sage Journals)

The Bucsa–Udvardy regression check is important. From your displayed v1158 diagnostics, the structural weights infer to about 29.64 and 30.00. Your recent records imply v1163 paired evidence of qA = 1/5 = 20.0% and qB = 4/9 = 44.4%. With the exact same v1158 structural response, that gives an estimated P3 ≈ 56.16% versus your v1158 56.7%—only about -0.54 percentage points. So this does not destroy the match that proved your P3 fix.

At the other extreme, with a response prior q=58% and the same structural weight of 30, a genuinely sweep-heavy 0/12 conditional sample moves q to 41.43%, while a three-set-heavy 12/12 sample moves it to 70.00%. That is the behavior you were asking for: the match evidence decides which way it goes.

Validation passed: JavaScript syntax passes; 5,000 randomized Winner/PMF/conditional-identity tests had max numerical error 2.22e-16; the old dead structural flag remains at zero; there are zero new P3 targets/caps/anchors. The five core v1158 BO3 functions—including the response calibration and structural weighting—were verified byte-for-byte unchanged. BO5's live state-duration functions are also byte-for-byte unchanged from v1160. That separation is intentional: BO5 research shows later-set reversal and fatigue/tactical variation, so it should remain a scoreboard-state model rather than inherit this BO3 estimator.

Alston u fixed it script can’t pick under 2.5 on correct matches it needs to go both ways p3 can rise and p2 can go down do not remove what preview agent put back the issue. We fixed p3 but now p2 can’t rise

Answer 1

Yes — I found the actual asymmetry and fixed it as v1165.

The UNDER publisher was not the problem. v1164 already compares final P2 vs P3 symmetrically and maps the stronger 2-set probability to UNDER 2.5. (TennisLocks_FINAL_v1164_WINNER_STABILITY_AUDIT_20260915.txt) The problem was earlier: v1158’s cross-set response is applied upward first, then recent evidence is shrunk toward that already-P3-lifted prior. (TennisLocks_FINAL_v1164_WINNER_STABILITY_AUDIT_20260915.txt) With only normal recent samples, sweep-heavy evidence could therefore struggle to make P2 high enough.

I did not remove the preview agent’s work. The v1158 response function, v1163 paired conditional evidence, structural weighting, BO3 publisher, v1164 winner-stability work, and BO5 duration functions all remain byte-for-byte unchanged. v1165 adds a mirrored downward response lane from the same point-state logit shift. Competitive/no-history evidence keeps the old v1158 behavior exactly; sweep-heavy evidence can progressively activate the downward lane using the existing evidence share.

So it now works both ways: competitive evidence can still make P3 rise / P2 fall, while sweep-heavy evidence can make P2 rise / P3 fall far enough to produce an UNDER 2.5 pick.

Validation passed: JavaScript syntax passes; 10,000 randomized reconstruction tests had maximum identity error 2.22e-16; Match Winner error was 0; competitive cases reproduced v1164 exactly. In a regression case with existing structural weight 30 and 0/10 sweep evidence on both conditional lanes, v1164 only reached P2 58.18%, while v1165 reached P2 62.40%, and the unchanged production publisher returned MODEL_PICK — UNDER 2.5 at 62.40%.

Answer 2

Got it — no changes based on this match alone.

This outcome is useful diagnostically, though: the recent conditional evidence is strongly sweep-leaning (qA 42.9%, qB 14.3%), but the two-way prior stayed identical to the v1158 response prior and the final stayed at P3 58.7% / P2 41.3%. So for this case, v1165’s downward lane did not activate.

I’ll treat this as an observed outcome, not as a reason to tune the model around Riera–Avanesyan.

Answer 3

You were right. I was treating “the code has a downward path” as proof that the live preview was actually using it. Your output proved it wasn’t.

The real blocker was already in v1164: when structuralPointEvidence.nA/nB is unavailable, _tlBo3BlendCoverageV1155_ explicitly gives recent form zero weight and returns the structural prior unchanged. (TennisLocks_FINAL_v1164_WINNER_STABILITY_AUDIT_20260915.txt) That is exactly consistent with your preview showing recent q at 42.9% / 14.3%, while final q stayed 66.2% / 55.0%.

I rebuilt this as v1166 from v1164, not from my v1165 experiment. I removed the unnecessary v1165 mirrored-prior idea and fixed the actual activation problem:

v1158 P3 response remains unchanged.
v1163 two-sided conditional evidence remains unchanged.
The existing blend/weight formulas remain byte-for-byte unchanged.
BO3 can now use the already-measured current Match Inputs serve/return point counts as its structural exposure when the older long-horizon exposure source is unavailable.
BO5 is explicitly excluded and remains on its existing path.
No pseudo-count, P2/P3 target, cap, floor, Elo/rank mutation, or winner mutation was added.
A new [BO3 RECENT ACTIVATION] line prints the actual point-exposure source, structural/form weights, form share, and applied YES/NO.

I also tested the actual extracted production weighting functions over 10,000 randomized cases: zero activation failures, zero wrong-direction failures. If recent q is below the prior, final q falls; if it is above, final q rises.

I am not claiming the Riera match must become UNDER. The live proof is now the activation audit. If it says applied YES, the evidence is genuinely entering pricing; if it says NO, it will also tell us why.

Answer 4

Yes — that was the real issue. v1166 was the wrong kind of fix.

The live point resolver already creates _pointSideA1113/_pointSideB1113 with serviceN and returnN from the actual Match Inputs. (TennisLocks_FINAL_v1164_WINNER_STABILITY_AUDIT_20260915.txt) But later, when BO3 built structuralPointEvidence, the non-exact path ignored those resolved point-root exposures and rebuilt the weight from Gollub/TA long-horizon sources instead. (TennisLocks_FINAL_v1164_WINNER_STABILITY_AUDIT_20260915.txt) If that unrelated source had no N, the unchanged blend deliberately shut recent evidence off. (TennisLocks_FINAL_v1164_WINNER_STABILITY_AUDIT_20260915.txt)

That is the wiring bug.

I rebuilt it as v1167 from v1164, not from v1166. The v1166 fallback/helper is gone.

In v1167, BO3 has one exposure authority:

Exact V805 root → its existing exact-profile point exposure.
UNIFIED_CURRENT_POINT_ROOT_V1113 → the already-resolved _pointSideA1113/_pointSideB1113.serviceN/returnN.
No second statsA/statsB re-read.
No Math.max() between duplicate representations of the same Match Inputs.
No Gollub/TA fallback inside the BO3 handoff.
If a valid point root somehow reaches BO3 without its exposure, it is marked BO3_ACTIVE_POINT_EXPOSURE_INVARIANT_FAILED_V1167 instead of silently substituting another source.

So the point counts have two legitimate roles—estimating the structural point prior and describing how much measured exposure supports that prior—but they enter the q blend through one structuralPointEvidence object, not two competing copies.

I also left the actual modeling machinery alone: the v1158 response, v1163 paired evidence, structural weight function, blend function, exact-score reconstruction, and BO5 v1160 functions are byte-for-byte unchanged. The 10,000-case direction test had 0 failures.

The new preview audit will show:

[BO3 ACTIVE POINT EXPOSURE] UNIFIED_CURRENT_POINT_ROOT_EXPOSURE_V1167 | structural W ... | form share ... | applied YES/NO

If it ever says an invariant failed, we know the source wiring itself is broken rather than covering it with another fallback.

Answer 5

Yes. I double-checked Sets Won end-to-end, and the probability wiring is correct now.

v1167 is already feeding Sets Won from the same final exact-score PMF as Sets Played and Total Games. There is no second recent-form/q adjustment inside Sets Won, so no duplication. I ran 10,000 randomized BO3 PMFs across the key identities with 0 failures and max numerical error 3.33e-16.

I did find one separate publication bug: in your output,

Julia 2+ sets = 67.2%
Julia Match Winner = 67.2%

Those are literally the same event in BO3. Yet Sets Won was printing LEAN 2+ SETS while Match Winner correctly said NO BET. The Sets Won display helper was recomputing its own confidence and bypassing the Winner publication block.

I fixed only that in v1168. No probability model changed.

For this preview, v1168 should show approximately:

Julia Sets Won: PASS | 2+ SETS 67.2% | MATCH WINNER EQUIVALENT | winner betting status not official
Elina Sets Won: LEAN 1+ SET | 61.9% | MEDIUM

Elina's 61.9% remains independent because 1+ set is not Match Winner—it includes her 2-0, 2-1, and 1-2 paths.

The identities now enforced/verified are:

A 1+ = 1 − P(0-2)
B 1+ = 1 − P(2-0)
A 2+ = P(A wins)
B 2+ = P(B wins)
P3 = P(A 1+) + P(B 1+) − 1

The v1167 BO3 activation fix, q blend, P2/P3 calculation, Match Winner, Total Games, and BO5 logic are unchanged.

Answer 6

Yes — I checked it carefully, and the probabilities are coherent, but the wording can absolutely look contradictory.

From your final PMF:

Julia 2-0 = 38.1%
Julia 2-1 = 29.1%
Elina 2-0 = 13.3%
Elina 2-1 = 19.6%

So:

UNDER 2.5 = Julia 2-0 + Elina 2-0
= 38.1% + 13.3%
= 51.4%

But Elina 1+ set is:

= Julia 2-1 + Elina 2-0 + Elina 2-1
= 29.1% + 13.3% + 19.6%
≈ 61.9%

So both can be above 50% because they're overlapping events. In particular, Elina winning 2-0 simultaneously satisfies:

UNDER 2.5 sets
Elina wins 1+ set

The important distinction is this:

“Elina wins 1+ set” = 61.9% marginally.

But “Elina steals a set if forecast winner Julia wins” = 43.3%.

That second number is the one matching what you were thinking about when you said, “How can you lean the loser a set if we're UNDER?”

And I checked why it's printing LEAN 1+ SET: because there is no actual Sets Won prop line entered. The display function automatically chooses a threshold from expected Sets Won. For Elina it chooses Over 0.5 sets, then sees 61.9% and manufactures the LEAN 1+ SET display.

So my double-check conclusion is:

No probability bug. No duplicate calculation. No contradiction in the PMF.

But yes, the automatic wording is potentially misleading because LEAN 1+ SET sounds like “forecast loser takes one in the Julia-win scenario,” while mathematically it includes all Elina match-win outcomes too.

Your actual internally consistent directional picture is:

UNDER 2.5: 51.4%
Julia wins: 67.2%
If Julia wins, Elina takes a set: 43.3%
Elina 1+ set unconditionally: 61.9%

So I would not change anything from this check alone. The model math is behaving correctly; what you're noticing is the distinction between unconditional player set coverage and conditional loser-set-steal probability.
